Serial No. 137,989.

This invention relates to an end support for a hollow roll construction and is particularly adapted for use in steel rolls, such as are employed in wet finishing and other textile finishing, paper machines and the like. These rolls are long and heavy and require firm support at each end.

The principal objects of the invention are to provide means whereby the rolls can be supported not only at their extreme ends but at a distance inside the end, either on a through shaft or a separate stud extending in from each end; to provide means whereby the shaft or studs can be accurately centered and firmly held in the rolls by holding means in the form of metallic discs; to provide these discs in such a form that they can be produced easily and cheaply and can be simply forced into the end of a roll which may be somewhat irregular or variable in inside diameter or surface and be left firmly fixed in the roll irrespective of such irregularities; to provide a construction sufficiently flexible for use under light, medium, and heavy service; to provide them with means whereby they can be welded to the roll to provide additional security; and to provide center hubs for different sized shafts.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 is a longitudinal central sectional view of one end of such a roll provided with a preferred embodiment of this invention;

Fig. 2 is a face view of one of the anchoring discs Fig. 3 is an edge view of a modified form of the same, partly in section, to show a different way of supporting it at the'center; and

Fig. 4 is a sectional view on the line 44 of Fig. 2, showing the parts much enlarged and indicating the way in which the disc is distorted in forcing it into the end of the roll.

The invention is shown in Figs. 1 and 2 as extends all the way through, or preferably a stud 11 at each end, with a plurality of pressed metal discs 12. Each of these discs is formed with a flat bottom and an up turned circular flange 13 extending around the same. This flange is formed originally in conical shape,as indicated in Figs. 2 and 4t and may be provided with a series of notches 14 cut out from the flange. Preferably they are of V-' shape and extend a material distance from the free edge of the flange inwardly. We have also shown these flanges asprovided with a series of perforations 15. At the center each disc is provided with an integral cylindrical bearing flange 16. WVe have shown the flat bottom as having a circular rib extending be: low the bottom all around for strength and to make the bearing longer. These parts are all formed in the act of shaping up these discs. We show one disc at the inner end of the stud and two at the outer end. The number used depends on the load carried and length of roll. I r

In operation the reduced end 18 of the stud 11 is forced into the bearing 16 of the inner disc and the outer discs are forced on the stud at another point and held by friction. This centers the discs on the stud. Now the stud is forced into the end of the pipe or roll centrally which has the effect of contracting the flanges 13 of the several discs as they are forced inwardly until they come to the cylindrical shape indicated in dotted lines in Fig. 4 and in full lines in Fig. 1. The metal yields and yet it springs back against the inner surface of the pipe or roll. The spring flange constantly applies a strong spring pressure to the roll, with its outer edge in position to resist removal. In this way the discs are held firmly in the pipe after being forced in.

The perforations 15 have rough edges which receive the metal of the pipe and resist any ordinary attempt to dislodge the parts. In addition to this we can spot weld the outer flange to the inside of the pipe in these perforations and the notches, if used, so that the disc is positively anchored. The pipe can be dented on the outside to depress the metal into these perforations thus further securing the parts together. This constitutes a very strong and durable construction. On account of having all the discs of the same diameter they can be forced into a pipe as it comes from the factory and will hold equally well.

It will be seen that the notches furnish two advantages when using thick metal discs. They assist the springing action described and their edges provide a convenient place for the welding like the perforations.

By making all the discs of the same diameter and tapering their flanges we are able to forcethe discs in under heavy pressure even though no recess is cut inside the tube or driven in and pressing against the surface of the same all around, said discs being located at a distance from each other along the shaft or stud and having perforations in the flanges and said roll being indented into said perforations for adding to the security with which the discs are held in the roll.

In testimony whereof we have hereunto af- (iXed our signatures. I

pipe and even though the inside is somewhat variable as to diameter and surface. The flanges spring in as they are forcedin under pressure and press against the surfaces of the pipe or roll with a heavy pressure.

In Fig. 3' we have shown a modification in which the notches 14 are eleminated. The notches are used chiefly in heavy constructions. In this figure also a hub 20 is placed on the stud at another point and held in the bearing 17 of; a single outer disc by set screws 21.

On account of'having the hub 20 in a form involving a substantial amount of material, preferably metal, the design can be adapted to a wide range of shafts or studs. The hubs 20 canbe replaced to provide for a shaft or stud of a different sizebut the inner disc is provided-with auniform passage as, whatever the diameter of the stud, it is turned down at the end tothis size. The idea can be employed with a shaft all the way through instead of studs, in which case we can use a different number of discs at each end, as for example, three or in some cases only one.

Although We haveillustrated and described only two forms of the invention we are aware of the fact that other modifications can be made therein by any person skilled the art without departing from the scope of the invention as expressed in the claims. There fore, we do not wish to be limited to all the details of construction herein shown and described but what we do claim is As an article of manufacture, a hollow roll provided with a shaft or stud having centered thereon a plurality of pressed metal discs. each having a surrounding tapering flange of such size as to be capable of being forced into the end of the roll withthe shaft or stud, said flanges being yieldable to conform to the shape and size of the interior of the rollwhen
